Major Features
--------------

'*Reactive Extensions':* Mono now bundles the open sourced Microsoft's [Reactive Extensions](http://rx.codeplex.com/)

**F# 3.0:** We have updated the bundled F# compiler on OSX to version 3.0 (tag 3.0.22 from the open source fsharp repository).

**SGen Garbage Collector:** new lazy sweep strategy in Mono's new GC that reduces the GC times for major collections significantly. We have also tuned and improved the collector.

**System.Json:** We reverted System.Json to Mono's version, as it was lighter and tolerates more input than Microsoft's one. We ship System.Json.Microsoft as well for users that want to use the Microsoft stack.

**Runtime:** Many improvements to Mono, better x86 and ARM support across the board.

**NTLM:** Large upgrade to our NTLM stack.

**clang:** Mono now builds with Clang.

**monodoc:** vast improvements to our documentation infrastructure.
